    Abstract: Disclosed is a method for the heterogeneously catalyzed partial gas phase oxidation of propene into acrylic acid, according to which a specifically composed initial reaction gas mixture containing propene and oxygen is oxidized on a first fixed catalyst bed having a constant or increasing volume-specific activity in the direction of flow in a first reaction stage. The resulting gas mixture of the first reaction stage, which contains acrolein, is then oxidized on a second fixed catalyst bed having an increasing volume-specific activity in the direction of flow in a second reaction stage. The molded catalyst bodies of both fixed catalyst beds have an annular shape and are respectively provided with a specific multimetal oxide composition.

    Abstract: A process for preparing acrolein or acrylic acid or a mixture thereof as a target product from propane, in which propane is dehydrogenated partially under heterogeneous catalysis in a reaction zone A, molecular hydrogen formed is combusted at least partly to water, any water present in the product gas A thus formed in reaction zone A is removed therefrom and product gas A is otherwise used to charge a reaction zone B in which propylene formed in reaction zone A is partially oxidized to the target product in the presence of remaining propane. The target product is removed from the product gas B formed in reaction zone B and propane present in the remaining residual gas is absorbed therefrom into a solvent and, after release from the absorbate, recycled into reaction zone A.

    Abstract: Conducting an exothermic heterogeneously catalyzed partial gas phase oxidation of an organic starting compound to an organic target compound in two different operating conditions I and II, comprises oxidizing a reaction gas starting mixture containing the organic starting compound, molecular oxygen and at least an inert dilution gas, through a solid bed catalyst present in the tube of a tube bundle reactor to produce a product mixture containing the organic target compound. Conducting an exothermic heterogeneously catalyzed partial gas phase oxidation of an organic starting compound to an organic target compound in two different operating conditions I and II, comprises oxidizing a reaction gas starting mixture containing the organic starting compound, molecular oxygen and at least an inert dilution gas, through a solid bed catalyst present in the tube of a tube bundle reactor to produce a product mixture containing the organic target compound; where: the tubes are surrounded by spaces for adjusting the reaction temperature; at least a fluid thermal carrier is passed in with an inlet temperature (Ti) and passed out with an outlet temperature (To) through the tubes; the outlet temperature is greater than the inlet temperature; the solid bed catalyst is charged with a load (L1) having the organic starting compound in an operating condition I at an inlet temperature (Ti1) and is charged with a load (L2) having the organic starting compound in the operating condition II at an inlet temperature (Ti2); the load (L2) is greater than the load (L1) and the inlet temperature (Ti2) is greater than (Ti1); the inlet temperature (Ti1) is elevated to the inlet temperature (Ti2) during the change of operating condition I to the operating condition II and subsequently the loading of the solid bed catalyst with the organic starting compound increases the (L1) value to the (L2) value.

    Abstract: Preparing acrolein and/or acrylic acid from propane comprises supplying two gaseous, propane-containing current to a first reaction zone A, under the formation of a reaction gas A; introducing the reaction gas A to a reaction zone A, supplying molecular oxygen and removing the product gas containing propylene, propane and water vapor; separating water vapor from the product gas A; feeding oxidation reactor with a reaction gas B containing propane, propylene and molecular oxygen and subjecting propylene to heterogeneously catalyzed, partial gas-phase oxidation. Preparation of acrolein and/or acrylic acid from propane comprises: (a) supplying at least two gaseous, propane-containing current (where one contains at least a fresh propane) to a first reaction zone A, under the formation of a reaction gas A; introducing the reaction gas A in the reaction zone A, formed through at least a catalyst bed by means of partial heterogeneous catalytic dehydrogenation of propane, molecular hydrogen and propylene, supplying molecular oxygen to the reaction zone A, where the molecular oxygen oxidizes a partial quantity of molecular hydrogen contained in the reaction gas A to form water vapor in the reaction zone A, and removing the product gas containing propylene, propane and water vapor, from the reaction zone A; (b) partially or completely separating, optionally in a first separation zone I, the water vapor contained in the product gas A by means of condensation incorporating indirect and/or direct cooling of the product gas A, while leaving behind a product gas Aa; (c) using the product gas A or Aa along with the supply of molecular oxygen, in a reaction zone B, for feeding at least an oxidation reactor with a reaction gas B containing propane, propylene and molecular oxygen, and subjecting the propylene contained in the reactor to heterogeneously catalyzed, partial gas-phase oxidation to form acrolein and/or acrylic acid as end product, and product gas B containing non-converted propane; (d) discharging the product gas B from the reaction zone B and separating the end product in a second separation zone II, while leaving behind a residual gas containing propane; (e) optionally reintroducing the partial quantity of the residual gas exhibiting the same composition of the residual gas as a propane-containing feed stream into the reaction zone A; (f) partially or completely separating the water vapor and/or the molecular hydrogen, in a separation zone III, which are possibly contained previously in the residual gas that is not fedback into the reaction zone A, by means of condensation and membrane separation processes respectively, and taking up the contained propane from the residual gas by absorption in an organic solvent under the formation of an absorbed substance that contains propane; and (g) separating the propane, in a separation zone IV, from the absorbed substance and reintroducing as propane-containing feed stream into the reaction zone A, where in the reaction zone A, at least lot of molecular hydrogen is oxidized to form water vapor, so that the hydrogen quantity that is oxidized in the reaction zone A to form water vapor amounts to at least 20 mol.% of the quantity of molecular hydrogen that is formed in the reaction zone A.

    Abstract: The invention relates to a method for the heterogeneously catalysed partial gas phase oxidation of acrolein to form acrylic acid, whereby the initial mixture of reaction gas is oxidised on a fixed-bed catalyst bed which consists of at least two fixed-bed catalyst bed zones and is arranged in two successive temperature zones A and B. The transition from temperature zone A to temperature zone B does not coincide with a transition from a fixed-bed catalyst bed zone to another fixed-bed catalyst bed zone.
